Brief Description of the Prior Art

Standard rotary drilling rigs are typically comprised of a supportiverig floor, a derrick extending vertically above said rig floor, and atraveling block that can be raised and lowered within said derrick.During drilling operations, this rig equipment is often used to insertand remove tubular goods from a wellbore situated under the derrickwhich extends into subterranean formations.

During downhole well operations, pipe (such as, for example, drill pipe,tubing, workstrings and the like) is typically inserted in wellbore, andremoved from such wellbore, in a number of sections of roughly equallength. These pipe sections, commonly referred to as “joints,” aretypically installed one at a time, and screwed together or otherwiseconnected end-to-end using threaded connections in order to make aroughly continuous length of pipe. According to industry convention, ajoint of pipe typically comprises a male or “pin-end” threadedconnection at its bottom end, and a female or “box-end” threadedconnection at its upper end; the threaded pin-end connection from onepipe joint can be connected to a threaded box-end connection of anadjacent pipe joint in order to mate or join said pipe joints together.

Continuous or “coiled” tubing represents an alternative to conventionaljointed pipe. Such coiled tubing typically utilizes a continuous length,up to 10,000 feet or more, of flexible tubing that is stored or wound ona reel. Unlike conventional jointed pipe, such coiled tubing can betranslated in and out of a wellbore in a virtually continuous mannerwithout the need to continually connect and/or disconnect individualpipe sections.

Coiled tubing can be used to conduct numerous downhole operations. Forexample, coiled tubing can be concentrically inserted into an existingwellbore in order to clean out sand or other debris from such well.Further, a fluid activated tool can be attached to the distal end of thecoiled tubing in order to perform work downhole; typically, pressurizeddrilling fluid can be pumped through the coiled tubing to actuate thedownhole tool. By way of illustration, a mud motor and drill bit can beattached to the distal end of coiled tubing and lowered into theborehole as the coiled tubing is spooled off a reel. As the mud motorextends deeper into the wellbore, pressurized drilling fluid drives thehydraulic mud motor which, in turn, rotates the drill bit downhole.

Although different manufacturing methods can be employed, coiled tubingtypically comprises an electric-welded tube manufactured with onelongitudinal seam formed by high-frequency induction welding without theaddition of filler metal. Although this seam often has a relatively lowprofile, the seam can nonetheless extend at least partially into theinner diameter of the coiled tubing. As a result, said weld seam canimpede the ability of a downhole tool (which is typically connected tothe distal end of the coiled tubing using a coil connector device) to bejoined to the coiled tubing forming a fluid pressure-tight seal. Assuch, it is frequently beneficial to remove a portion of this seam or“dress off” the distal end of the coiled tubing in order to create asubstantially smooth inner surface of said coiled tubing in order topromote a “flush” or fluid pressure seal between a downhole tool (orcoil connector) and said tubing. In many cases, such dressing off mustbe done in the field immediately prior to performing desired coiledtubing operations.

Thus, there is a need for a method and apparatus for removing at leastsome portion of a weld seam, or other obstruction or debris, from theinner surfaces of a section of coiled tubing. The method and apparatusshould be relatively inexpensive, easy to use and effective, therebyallowing use in the field, or in a shop or other facility.

SUMMARY OF THE INVENTION

The present invention comprises a seam dressing tool assembly for use inbeneficially removing a weld seam on a section of coiled tubing, andthus, preparing an inner surface of said coiled tubing for an effectiveseal with a coil connector, or any other similar connecting device. In apreferred embodiment, the seam dressing tool of the present inventiongenerally comprises a receiver, or sleeve, member, a drive shaft member,a drive collar member, a seal member, and a bit member.

In a preferred embodiment, the seam dressing tool of the presentinvention comprises a drive shaft member. Said drive shaft comprises asubstantially cylindrical body member, having a first end and a secondend and an outer diameter. Said first end of the shaft member comprisesa receiving end for a drive motor mechanism, or any other similarmechanism, such as, for example, an air winch, and said second end ofthe shaft member allows for a connection with a bit member. Said bitmember comprises a plurality of teeth-like projections (i.e, a carbidecutter with a plurality of honey comb inserts) located along an outersurface of said bit member for use in cutting a seam out and thusbeneficially removing a weld seam from an inner surface of a section ofcoiled tubing. Thus, said bit member is threadably connected to secondend of drive shaft member and is slidably disposed and received within adistal end section of coiled tubing. Thus, as said bit member and saiddrive shaft member are axially moving within said coiled tubing, saidbit member is powered by said drive motor mechanism, thereby rotatingsaid bit member about its axis, and thus removing said weld seam fromwithin said coiled tubing.

Additionally, the seam dressing tool of the present invention comprisesa drive collar member for use in maintaining control over said shaftmember, and thus, keeping said shaft member substantially stable whilesaid seam dressing tool assembly is in operation. Said drive collarcomprises a first end and a second end, wherein said first end allowsfor said drive shaft to be received within said drive collar and saidsecond end of said drive collar attachably connects to said receivermember. Said receiver member comprises a substantially cylindrical bodymember having a first end, a second end, an inner surface, and an outersurface, thus defining an inner chamber, wherein said first endattachably connects to said drive collar and said second end attachablyconnects to a receiver cap. Said receiver cap beneficially allows saidreceiver, and thus, said seam dressing assembly of the presentinvention, to connect to a distal end of said coiled tubing.

In a preferred embodiment, the seam dressing tool of the presentinvention further comprises a first seal member and a second sealmember, or an O-ring, for use in preventing any excess fluid fromexiting said coiled tubing while said seam dressing assembly is inoperation. Said first seal member is adjacently disposed around saidouter surface of said drive shaft and is positioned adjacently to saidsecond end of said drive collar. Further, an outer surface of said firstseal member is adjacently disposed about and positioned against saidinner surface of said receiver member. As a result, said first sealmember creates a plug or barrier in order to prevent any excess fluidfrom exiting said coiled tubing. Said second seal member, or O-ring, andat least one O-ring spacer are disposed within a groove between saidreceiver member and said receiver cap, and thus, effect a seal betweensaid receiver cap and said receiver member. As a result, said O-ring isheld in place using said O-ring spacers and a threaded connectionbetween said receiver member and said receiver cap.

In a preferred embodiment, when said seam dressing assembly is inoperation, a distal end of a section of coiled tubing is received withina second end of a receiver cap, wherein said receiver cap attachablyconnects said seam dressing assembly to said coiled tubing. Said driveshaft is attachably connected to a first end of said receiver member byway of said drive collar member. Thus, said drive collar member isthreadably connected to said receiver member, thereby stabilizing saiddrive shaft during operation. Further, when said drive shaft isconnected to said receiver, a rubber seal member, or O-ring, isadjacently disposed between said drive collar member and said receivermember, thereby creating a plug in order to prevent any fluid fromexiting said coiled tubing. As such, said seam dressing assembly cansafely be used in and/or around water, or other similar liquids, asnecessary.

A user is then able to manually hold said receiver in order to providestability to said seam dressing assembly, while a drive motor mechanismis attachably connected to said first end of said drive shaft member.Said drive motor mechanism is then able to power and thus apply arelative force to said drive shaft member, and thus ultimately, to saidbit member. When said drive shaft axially extends into said distal endof said coiled tubing, said bit member extends into and through saidreceiver, and thus, into an inner chamber of said distal end of saidcoiled tubing. As a result, said bit member is able to rotate about itsaxis, contact the inner surface of said coiled tubing, and thus remove aweld seam along said inner surface of said coiled tubing. Therefore,said bit member is further able to clean up any rust, debris, or anyother deviations from within said inner surface of said coiled tubing.After said weld seam has been removed, said seam dressing assembly ofthe present invention can be disconnected and removed from said distalend of said coiled tubing, and then any desired coil connector can beattached to said coiled tubing, as necessary.

Additionally, in a preferred embodiment, the seam dressing assembly ofthe present invention further comprises an inner diameter (ID) bevelerapparatus for use in removing any excess deviations from within asection of coiled tubing prior to the attachment of the seam dressingtool assembly of the present invention. Thus, said ID beveler apparatusis generally used prior to said seam dressing assembly of the presentinvention. Said ID beveler apparatus generally comprises a beveler driveshaft, a beveler collar, and a beveling cone. The ID beveler apparatuscan attach to a distal end of a section of coiled tubing andbeneficially trim an internal diameter of said coiled tubing to adesired size by way of said beveling cone.

In a preferred embodiment, when said ID beveler apparatus is inoperation, if said coiled tubing is to be connected to an inner diameterconnector, or any other similar tool, said ID beveler apparatus can beattached to a distal end of said coiled tubing, trim said inner diameterof said coiled tubing as needed, and thus prepare said distal end ofsaid coiled tubing to be connected to said seam dressing tool assemblyof the present invention in order to further remove a weld seam fromwithin said inner surface of said coiled tubing. After said seamdressing tool assembly is disconnected from said coiled tubing and saidweld seam has been removed, said coiled tubing can then be connecteddirectly to an inner diameter connector, as necessary.

Additionally, in a preferred embodiment, the seam dressing assembly ofthe present invention further comprises a plug member for use in sealingoff a pipe before said seam dressing assembly is able to remove a weldseam from a section of coiled tubing, thereby preventing any water andor debris from coming in contact with said seam dressing assembly of thepresent invention. Said plug member comprises a threaded rod, aplurality of washers, and a plurality of—typically two (2)—O-rings. Saidplug member is manually placed within a section of pipe and is thenforced further down into said pipe by way of a variety of differenttools. Said plug is forced far enough into said pipe to go beyond asection that needs to be dressed; thus, said plug is forced into saidpipe beyond a distance where said weld seam is to be removed, and thensaid seam dressing assembly of the present invention is inserted intosaid pipe in order to remove said weld seam, as necessary. As a result,the O-rings of said plug create a barrier within an internal diameter ofsaid pipe, thereby preventing any water, or fluid, and any type ofdebris from coming in contact with said seam dressing assembly as saidassembly is removing the weld seam from said coiled tubing.

First end 11 of drive shaft 10comprises a receiving end for a drive motor mechanism (although notillustrated in FIG. 1), or any other similar mechanism or power source,such as, for example, an air wrench, and second end 12 of drive shaft 10comprises a receiving end, or a connection point, for bit member 30.

In a preferred embodiment, outer diameter 14 of drive shaft 10 comprisesa plurality of circular-shaped grooves 16 that surround an entire outercircumference or surface 14 of shaft member 10 and that areequidistantly spaced apart along outer surface 14 of shaft member 10. Asa result, grooves 16 provide depth markings in order for a user tovisually determine how far drive shaft 10, and thus, seam dressing tool100, is being slidably disposed and extending within a section of coiledtubing.

Drive collar member 20 comprises a means for maintaining stabilitywithin seam dressing tool 100, and thus, keeping drive shaft 10substantially controlled. Drive collar 20 comprises a first end 21, asecond end 22, an inner diameter, or surface 23, and an outer diameter,or surface 24, wherein drive shaft 10 is received within first end 21 ofdrive collar 20 and second end 22 of drive collar 20 comprises athreaded connection 60, or any other similar attachment means, in orderto attachably connect drive collar 20 to receiver member 40.

Second end 32 ofbit member 30 comprises a substantially jagged head member 33 having asubstantially rough outer surface for use in removing a weld seam, orany other debris, from within a section of coiled tubing. Head member 33has an outer diameter that is approximately slightly less than an innerdiameter of a section of coiled tubing, thereby allowing head member 33to be received within and extend through said coiled tubing, and thus,axially move along inner surface of said coiled tubing. Further, headmember 33 comprises a plurality of fan-like projections 34 equidistantlyspaced along an outer surface of head member 33, wherein saidprojections 34 further comprise a plurality of teeth-like protrusions35. Said teeth-like protrusions 35 thus allow bit member 30 to contactsaid inner surface of said coiled tubing, and thus, remove said weldseam from said inner surface of said coiled tubing. For example, saidfan-like projections 34 comprising a said teeth-like protrusions 35 cangenerally be referred to as a carbide cutter having a plurality ofhoneycomb inserts. Said cutter allows said bit member 30 to cut saidweld seam from said inner surface of said coiled tubing.

Still referring to FIG. 1, in a preferred embodiment, receiver member 40comprises a substantially cylindrical-shaped configuration, having afirst end 41, a second end 42, an inner diameter, or surface 43, and anouter diameter, or surface 44. First end 41 of receiver member 40comprises a threaded connection 60, or any other similar attachmentmeans, wherein drive collar 20 can attachably connect to receiver member40, and thus, ultimately allow drive shaft 10 and bit member 30 to bereceived within and extend through receiver member 40. Second end 42 ofreceiver member 40 comprises a threaded connection 60, or any othersimilar attachment means, for attachably connecting receiver member 40to a receiver cap 45. Receiver cap 45 further comprises a first end 46,a second end 47, an inner surface 48, and an outer surface 49, whereinfirst end 46 of receiver cap threadably connects to second end 42 ofreceiver 40.

Inner diameter 51 of first seal member 50 sits directlyadjacent about outer surface 14 of drive shaft member 10. Outer diameter52 of first seal member 50 sits directly adjacent along inner surface 43of receiver member 40, thereby creating a seal in order to prevent anyfluid from escaping or exiting from said coiled tubing when receiver 40is attachably connected to said coiled tubing. As a result, first sealmember 50 effects a seal between drive collar 20 and receiver member 40.

Additionally, seam dressing assembly 100 comprises a second seal member,or an O-ring 55, and at least one O-ring spacer 56. O-ring 55 and O-ringspacer 56 each comprise a substantially circular, ring-like devicehaving an inner through bore 57.

Still referring to FIG. 5, first end 31 of bit member 30 can bethreadably connected to second end 12 of drive shaft member 10, whereinbit member 30 is joined to drive shaft member 10 in an opposingend-to-end relationship. Second end 32 of bit member comprises headmember 33 for use in removing a weld seam from within a section ofcoiled tubing. Head member 33 has an outer diameter that isapproximately slightly less than an inner diameter of a section ofcoiled tubing, thereby allowing head member 33 to be received within andextend through said coiled tubing, and thus, axially move along innersurface of said coiled tubing. Further, head member 33 comprises aplurality of fan-like projections 34 equidistantly spaced along an outersurface of head member 33, wherein said projections 34 further compriseteeth-like protrusions 35 located along an outer surface of saidprojections 34.

FIG. 6 depicts a perspective view of seam dressing assembly 100 of thepresent invention in operation. When in operation, a distal end of asection of coiled tubing 90 is received within second end 47 of receivercap 45, and thus, coiled tubing 90 is attachably connected to receivercap 45 by way of threaded connection 60, or via any other similarattachment means. Drive shaft 10 is attachably connected to first end 41of receiver member 40 by way of drive shaft collar 20. Drive shaftcollar 20 is attachably connected to first end 41 of receiver member 40by way of said threaded connections 60, thereby stabilizing drive shaft10 during a seam dressing operation. When drive shaft collar 20 isconnected to receiver member 40, seal member 50 is also received withinreceiver member 40, thereby creating a plug in order to prevent anyfluid from exiting coiled tubing 90 while seam dressing tool 100 is inoperation.

In a preferred embodiment, a user is able to manually hold receiver 40in order to provide stability to said tool 100, while drive motormechanism 150 is attachably connected to said first end 11 of said driveshaft member 10. Drive motor mechanism 150 is then able to power andthus apply a relative force to drive shaft member 10, and thusultimately, to said bit member 30, as drive shaft member 10 and bitmember 30 are being powered into coiled tubing 90. As a result, saidpower provided by said drive motor mechanism 150 enables drive shaft 10to slidably extend through receiver member 40 and thus through saidcoiled tubing 90, ultimately allowing bit member 30 to extend throughreceiver member 40 and through coiled tubing 90.

Further, when drive shaft 10 axially moves into and extends throughcoiled tubing 90, bit member 30 axially extends into and throughreceiver member 40, and thus, into and through an inner chamber ofcoiled tubing 90. Bit member 30 is then able to rotate about its axis,contact the inner surface of said coiled tubing, and remove weld seam 95within the inner surface of coiled tubing 90. Therefore, bit member 30is further able to clean up any rust, or any other similar deviationsfrom within inner surface of coiled tubing 90. After weld seam 95 hasbeen removed, seam dressing tool 100 can be disconnected and removedfrom said distal end of coiled tubing 90, whereby any desired coilconnector can then be attachably connected to coiled tubing 90, asnecessary.

FIG. 7 depicts a preferred embodiment of an inner diameter (ID) bevelerapparatus 200 for use in removing any excess deviations from within asection of coiled tubing prior to the attachment of seam dressingassembly 100 of the present invention.
